About
Loop Library is a curated collection of agent loops — reusable prompting patterns and workflows you can plug into AI coding and automation agents right now. It aggregates community-submitted loops like refactoring workflows, live-testing cycles, and review patterns. It's useful for developers who want to level up their AI agent usage without starting from scratch.
What it does
Matthew Berman's launch post on X presents Loop Library as a curated list of agent loops: short standing instructions that keep a coding agent cycling through steps. Readers can browse loops and submit their own. His example, credited to Peter Steinberger, refactors, live-tests, runs autoreview and commits after each step.
